Page 10 Installing and Supporting MegaRAID Storage Manager Software on VMware This section documents the installation of the MegaRAID Storage Manager software on VMware ESX (also known as Classic) and VMware ESXi operating systems. Installing MegaRAID Storage Manager Software on VMware ESX (VMware Classic) VMware does not support any graphic components and hence you can install only the server component of the MegaRAID Storage Manager software.
Page 11 software. Management is performed through the MegaRAID Storage Manager software installed on a remote machine (Linux/Windows). VMware ESX 4.0 comes with the Small Footprint CIM Broker (CFCB) CIM Object Manager (or CIMOM). A CIMOM manages the communication between providers, which interact with the hardware, and a CIM client, where the administrator manages the system.

The MegaRAID Storage Manager software disables drive security and returns you to the main menu. Note: If you disable drive security, you cannot create any new encrypted virtual drives and the data on all encrypted unconfigured drives will be erased.
Page 151 In addition, if one or more drives are removed from a configuration, by a cable pull or drive removal for example, the configuration on those drives is considered a foreign configuration by the RAID controller. Verify whether any drives are left to import as the locked drives can use different security keys. If there are any drives left, repeat the import process for the remaining drives.
